COMBINED MARKING LAND SPOOLING MACHINE FOR MUSIC-ROLLS.

Specification of Letters Patent.

Patented Oct. *7, 1913.

Application filed January 18, 1911. Serial No. 602,760.

To all whom it may concern Be it known that I, GEORGE HOWLETT DAVIS, a citizen of the United States, residing in the town of Vest Orange, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Combined Marking and Spooling Machines for Music-Rolls; and I declare the following to be a full, clear, and exact description of same, such as will enable others skilled in the art to which it pertains to make, construct, and use the same.

In my prior Patent No. 968,136, granted August 23, 1910, I have described and illustrated a machine for spooling the sixteenply perforated sheets as they have passed through the perforating machines, which latter machines are well known in the artand need no specific description. In the manufacture of perforated music rolls or sheets it is obviously advantageous to perform as much labor upon the multiple sheets while they are held together as it is possible to do so consistent with the kind and character of labor to be put upon them. Many devices have been proposed for placing upon the music sheets the indicating marks, such as the dotted expression mark or line,

the sinuous tempo-line, and certain other marks indicating musical expression, while the multiple sheets are held together 1n the condltlon in which they leave the perforating machine; but for some one or other reasons these devices have not proved success ful in practice and have been discarded with the result that at the present time manufacturers are using the single method plan, that is, marking each individual roll separately.

It is the present practice with perforating machines when perforating 65-note music to perforate sixteen separate sheets simultaneously, and when perforating SS-note music to perforate a less number, usually ten sheets simultaneously. It will thus be seen that if each one of the sheets of the cutting is to be marked separately, the work must be multiplied from ten to sixteen times.

It is the purpose of my improvement hereinafter to be described to obviate the neces sity of this single marking system and to provide a machine whereby an entire set of cuttings, that is, either ten or sixteen single cuttings maybe simultaneously marked in accordance with a single-marking model;

this marking may be done as rapidly as the perforating sheets emerge from the perforating machines, or the cuttings may be allowed to accumulate as described in my above named patent, and the trays containing such accumulated cuttings may be placed beneath'my new machine and fed thereinto with a result that when the steps of the operation contemplated are completed the -en tire set =of cuttings will not only be pro.-

vided with the individual expression marks but also wound up'in roll form ready for spooling. Thus this improvement mechanically performs the work of from ten to sixteen operatives in far less timeand with a greater degree of precision and uniformity. Further, in manufacturing plants where floor space is-va-luable, the old plan of single marking occupies a separate table for each roll to be marked and eachtable occupies'even more space than my improved marking and spooling machine. will be seen is a very decided advantage where floor space isvaluable.

In working outmy invention I have utilized many of the features illustrated and described in my above named patent, in fact,

it may be said that the'essential features of the re-spooling machine remain the same and that the markingdevice has been added thereto.

' I will now proceed to describe in detail the mechanism forming my invention.

Figure 1 is a side elevation, partly in section, ofmy invention. Fig. 2 is a plan View of the same. Fig. 3 is a side elevation, partly in section, of .a single marking unit. l is a section on line t, 4t of Fig. 3. Figs. 5 and 6 are respectively side and rear view of the combined pointer and circuit breaker. Figs. 7 and 8 are respectively end views, partly in section, of the machine, showing the relative position of the marker frame operating shaft, with respect to the other parts of the machine. Fig. 9 illustrates a detail.

The same reference numerals refer to like parts throughout the specification and dr y ings.

As above indicated my invention has been engrafted upon the structure substantially as illustrated in my above named Patent No. 968,136, to which specific reference is made, for the details thereof in order to avoid repetition. The only material differences reside in-thefact that table 16 with its guides This, it

, 17 and guide spindles or rollers 19, instead a series of idler or guide spindles 27 one adjacent to each of the spindles 2 1, for a purpose hereinafter to be described. Utherwise the details of construction so far as the device illustrated in Patent No. 968,136 is concerned are preserved.

The upper part of the frame 1 is provided wit-h extensions 23, 29, upon which are mounted the guides 30, 31, respectively. These guides consist simply of flat plates and 2 plates spanning from one side of the upper timbers of the frame to the other. Within these guides are located the flat plates 32, 33, which form supports for the marking device hereinafter to be described. Secured to the under side of each one of the plates 32, 33, are the racks 34., 35, said racks meshing with the spur gears 36, 37, the latter being mounted upon the ends of a horizontal shaft 38 which extends from one end of the frame to the other, as shown, being mounted in the bearings 39, 40, the latter being located in the cross-timbers of the frame 1. The shaft 38 is provided adjacent to the bearing $0 with a bevel gear 41, which meshes with a similar gear 42, mounted upon a horizontal shaft 43, carried in suitable bearings upon the frame and provided at its outer extremity with a crank 4 It will thus be seen that the turning of the crank 1 1 will cause a rotation of the shaft 38, and a consequent, simultaneous, and uniform movement of the two plates 32, 33, in the guides 30, 31. Secured upon the upper sides of the two plates 32, 33, are the two arch shaped marker supports 45, 46; these supports being formed upon a semi-circle somewhat larger than the spindle supporting frame 2, so that when the plates 32, 33, slide back and forth in their guides 30, 31, the marker supports 45, 46, are compelled to move laterally or in a direction parallel to the axes of the spindles 24. Located between the two supports 45, 46, at intervals throughout their length, so as to be adjacent to the spindles 2d, are the marking devices which I will now proceed to describe. Inasmuch as all of the marking devices are alike, a description of a single one of them is deemed sufficient.

Each marking device consists of a solenoid magnet mounted upon a U shaped bracket 4:7, the legs of which are secured respectively to the plates 45, 46, by means of the bolts 43 and wing nuts 49, said bolts passing through slots 50 in the plates 45, 4:6

so that the bracket 47 may be adjustably se cured to the plates 15, 46. Secured to the underside of the bracket 47 is the solenoid magnet 51 having the central axial rod 52 passing therethrough, said rod being pro vided at its upper end with an armature 53. Beneath the head of the armature I locate a small coil spring 54, the tendency of which is to hold said armature away from the end or pole of the magnet, the distance, of course, being limited by means of the collar 55 upon the rod 52 just outside the lower end of the magnet. I mount a rotatable dotting wheel 56, upon a short stub shaft 57, which is journaled in the lower end of the rod 52. The rotation of the clotting wheel is efiected by the means of a ratchet wheel 58 and a pair of spring pawls, one of which, 59, is secured to the lower end of the magnet, while the other pawl, 60, is secured to the rod 52, as clearly shown in Fig. 3. It will thus be seen that the reciprocation of the rod 52 under the influence of the magnet 51 will cause a step by step rotation of the dotting wheel 56, inasmuch as the pawl 59 will engage successively the teeth of the ratchet wheel 58 at each reciprocation while the pawl 60 will serve to prevent excessive rotation or rotation beyond a single step. Secured adjacent to the clotting wheel in any convenient manner, as by means of the arms 61, is the rotating inking wheel 62 with its periphery bearing upon the clotting projections of the wheel 56. It should be understood that the inking wheel 62 freely rotates in contact with the wheel 56 so as to provide a fresh supply of ink for each one of the dotting projections in succesion.

From a reference to Fig. 3 it will be noted that the idler or guide spindles 27 are mounted in the circular frame 2 in a position between adjacent take-up spindles 24, and that the perforated rolls pass over such idler or guide spindles 27 before being wound upon the spindles 2t. The dotting wheel 56 together with a dotting apparatus is located upon the frame 45, 46, in a position so as to be immediately adjacent to the periphery of the spindles 27, in order that the dotting projections on the wheel 56 may mark the perforated rolls 23 just as they pass over the idler spindles 27.

In practice a marking model perforated roll 63 is provided upon which the exact line to be duplicated upon the perforated rolls is carefully delineated. This marking model is in all respects a pattern, having note perforations of the same note value as are found in the perforated rolls and it is used as a guide for duplicating either the expression-line or tempo-line upon the completed perforated roll. This marking model must therefore be matched up with the set of perforated rolls 23 at as nearly as possible the time said rolls are threaded into the machine.

This may be done by laying such roll with its model line face downward upon the entire set of cuttings which are then located in the tray 22, as clearly shown in Fig. 1. The marking model, however, is not threaded through the machine in the same manner as the remaining perforated rolls 23. Being upon the top or outside of all the other perforated sheets this roll 63 is carried over a pair of take-up rolls 64, 65, thence across a table 66 and around a guide roll 67 to a takeup spindle 68, the latter being driven by the same power as the other spindles 24: and at identically the same rate of speed.

In actual practice the marking model is usually a cutting made from some master from which all of the perforated sheets to be marked have been cut and the marking model may or may not perfectly register with the perforated sheets to be marked so far as the perforations go. The matching up heretofore referred to is, therefore, done as nearly as it is possible to match up the perforations of the marking model with the perforations in the sheets to be marked. This deviation of registry between the marking model and the perforated sheet is common, and may be accounted for by a slight change in the feed of the perforating machine at different times, or variations in the quality or texture of the paper resulting in greater or less degrees of expansion or contraction under atmospheric changes. Some means must, therefore, be provided for adjusting the marking model back into registry with the perforated sheets as they travel through the machine. This deviation is observed by the operator from the location of the pointer, hereinafter referred to, with respect to some particular perforation in the marking model and the position of the dot ting wheel 56 with respect to the corresponding perforation in the perforated sheets 23, as they pass over the idler spindle 27. The means for adjusting this registry will now be explained. As heretofore stated this marking model 63 is laid with its model line face downward upon all the rest of the sheets 23 before said sheets are threaded into the machine, so that when it is threaded into the machine its model line will appear face upward upon the table 66. Inasmuch as this line is to be followed as a model or pattern from which all of the other rolls are to be marked, it is necessary that the particular pointin the line which is to be followed by a pointer must be somewhat advanced, and to provide for this advance the two take-up rolls 64, 65, are interposed so that the pointer hereinafter referred to will be located just over a point in the line in the marking model which will correspond exactly to the point in the perforated sheets 23 which will pass over the idler spindles 27. Some means mustnow be provided for ad justing these take-up rolls so that the model line and the note perforations will correctly register both in the marking model and in the perforated sheets 23 as the latter are marked. This adjustment is provided in the following manner: 69 represents the bearings for the take-up roll 65, the journals of which extend laterally outside of said bearings and have mounted thereon the links 70, one of which, namely, upon the front side of the machine, extends into an arm 71 which engages a ratchet rack 7 2 for holding said arm 71 in any desired position. It will thus be seen that when the arm 71 is moved around the rack, the link portion thereof, will carry the take-up roll 64; wit-h it and thereby take up more or less of the length of the marking model 63, so .as to bring the particular point in the model line on the marking model above the table 66.

I will now proceed to describe the pointer which is designed to follow the model line upon the marking model.

Upon reference to Fig. 1, it will be noticed that the take-up spindle 68 is spaced away from the last one of the take-up spindles 24L. Projecting through this space is the arm 7 2, the upper end of which is secured to the frame plate 46, as shown, the forward end of said arm 7 2 being bent downwardly so as to bring its lower end to a point slightly above the table 66. Secured to the lower end of this arm 72 is a swiveled wheel 72 some what offset from the axis of the lower end of the arm 7 2 in the manner of the ordinary bed caster. This wheel is permitted to contact with the marking model as the same travels over the table 66, and in order to provide for easy swiveling I have mounted the wheel shank 73 upon ballbearings, as shown; any convenient style of ballbearings which will provide for easy turning of the shank 73 upon the lower end of the arm 7 2 may be used.

The wheel 7 2 is of peculiar construction. It is comparatively broad faced, having a groove in the center thereof in which is mounted a rubber ring 74:, and upon each side of said ring in the face of the wheel I provide at uniform intervals insulation 7 5, as shown. Bearing upon the face of the wheel 72 and on either side of the rubber ring 74-, are the two contact springs 76, which are separately mounted upon a lateral projection 77 with the insulation 7 8 interposed to provide against eross-circuiting. From each of the contact springs 76, 76, respectively are led circuit wires 7 8 7 9, which wires are led along the arm 72; one of them leading to one pole of a battery or other source of electric power 80 through a single pole switch 81, and thence along the frame plate 46, adjacent to the series of magnets 51. The other wire 78, is led along the plate 46 parallel to the first named wire.

Short shunt wires 82, 83, are led from the wires 78 79, to each of the magnets as clearly shown in Fig. 3.

From a reference to my above named Patent No. 968,136, it will be seen that the per forated sheets 23 are simultaneously wound upon the spindles 24 by turning the crank upon the shaft 6, the motion being communicated to all of the spindles through the belt 9. As shown in the drawings this belt 9 pass-es over the corresponding pulley which drives the take-up spindle 68. Consider now that the machine is now all. threaded up as clearly illustrated in Fig. l, and that it is desired to mark each one of the rolls 23 in accordance with the line on the marking model 63. The operator will first manipulate the crank 4d, and thereby bring the frame plates 45, 46, into a position so that the wheel 72 will be immediately over the model line on the marking model 63. The operator then with the crank 4A in the one hand to manipulate the position of the arm 7 2 to follow this line, grasps the crank on the shaft 6 with his other hand, rotates said crank to wind up the perforated rolls 23 upon their respective spindles and also the marking model sheet 63 upon its spindle 68. As this marking model 63 travels over the table 66 the operator manipulating the crank 44; will cause the wheel 72 to follow the model line on the marking model 63, but inasmuch as the rubber ring 74 causes the rotation of the wheel 72 as the marking model travels under such wheel, the electric circuit through the series of magnets will be opened and closed as the metallic points in the wheel 72 and the insulation 7 5 pass under the contact springs 76, 76. This will cause a simultaneous make and break in the circuit and a consequent simultaneous actuation of each of the magnets 51, to cause the dotting wheels 56 to be reciprocated against the perforated sheets 23 as they pass over the idler spindles 27. Any deviation in the line on the marking model. will be carefully follow-ed by the operator manipulating the crank 44, so that as the pointer 72 follows the line it is clear that the dotting wheels 56 will be moved parallel to the axes of the spindles 24c, and the reciprocation of such dotting wheels through the means of the magnets 51 will cause an exact duplication upon the entire set of perforated rolls 23, of the line upon the marking model 63.

All of the features relative to the uniform tension in the perforated rolls 23 referred to in my prior Patent No. 968,136, are maintain-ed in the structure just described and when the rolls 23 are completely wound up as is described by my present improvement they are also completely marked in accordance with the marking model.

I have shown this marking device as being a separate and distinct machine from a perforating machine, but I wish it to be un derstood that the set of perforated rolls 23, instead of being stored up in the trays 22, as illustrated, in Fig. 1, may be taken directly as they emerge from the perforating machine. This is in fact the better way of utilizing this improvement for the reason that as the set of sheets 23 emerge from the perforating machine and are held under uniform tension there can be no shifting of the individual rolls 23 among themselves and the result of the marking will be exactly uniform throughout. As an example of such perforating machine I wish to refer to my prior Patent No. 659,053, granted October 2, 1900, wherein I have shown the complete perforating machine for perforating music sheets, either singly or in gangs.

In my Patent No. 747,687, dated December 22, 1903, I have shown a device for simultaneously marking a plurality of rolls from a single marking model. In practice the machine of this patent operated admirably upon a limited number of sheets which however had to be separately spooled prior to the marking operation. With an entire cutting of from ten to sixteen-rolls, however, two or three operatives and sometimes more, are required to keep all of the separately spooled rolls in correct registry with the marking model so that the zigzag or sinuous line to be duplicated upon the perforated music sheets would register correctly with corresponding note slots. My present device obviates all these difficulties and makes it possible for a single operative to accurately mark an entire cutting of sixteen rolls, but at the same time spool the entire set of sheets as they leave the perforating machine. The perfect registry of all of the sheets of the cutting is maintained by keeping them in gangs with their edges clipped together by ordinary paper clips as they emerge from the perforator when, of course, the entire gang must be in exact registry. These clips are removed prior to the passage of the gangs of sheets between the tension rolls, 10, 11, and the registry is maintained by these tension rolls.

The are upon which the frame 2 is struck is not an exact circle, but approaches the circle very closely. It is really a double involute of the two rolls 1O, 11, so that the distances from the point between said rolls (their point of tangency) where the sheets 23 begin to separate or radiate to the point where they pass over the idler spindles 27, are the same for all of the sheets. It will thus be seen that the registry of the note slots having been maintained up to the tension rolls 10 and 11, such registry as the sheets pass over the idlers 27, will be preserved, and since all of the dotting wheels are actuated in unison the resulting zig-zag or sinuous line will be identical upon all of the sheets, and correctly register in its deviations with the note slots of said sheets. The adjusting take-up 64, 65,.as above described, provides for the adjustment of the registry of the perforated sheets 23 with the marking model 63. It will thus be seen that I I am able by asingle machine, handled by a single operative, to accomplish what has heretofore required from four to sixteen operatives to accomplish, while the work done is much more accurately and quickly done.
